To all whom it may concern.-

Be it known-that I, PAUL MAUSER, a subject of the King of VViirtemberg,Empire of Germany, and a resident of Oberndorf-on-the- Neckar, in theKingdom of VViirtemberg, German Empire, have invented a certain new anduseful Cartridge-Shell Extractor with Radial Guides for Breech-LoadingBolt-Guns, of which the following is a specification.

This invention is the subject-matter of Letters Patent in Germany, N0.49,87 7 dated July 3, 1889; in Belgium, No. 86,375, dated May 25, 1889;in England, No. 18,01 1, dated November 12, 1889; in Italy, No.26,450/137, dated December 31, 1889, and in Spain, No. 10,226, datedFebruary 1, 1890.

This invention relates to that part of a boltgun which is designed fordrawing the shells of the exploded cartridges out of the gun-barrel, andwhich is usually termed an extractor, and the invention comprises moreparticularly certain improvements in such extractors whereby the latterare rendered re.- liable in action and strong and simple inconstruction.

The invention is intended primarily for bolt-guns the bolts of which areprovided with recoil or looking projections on their front ends, andwhich do not have separate boltheads. It may, however, be applied toboltguns the bolts of which have a separate head, if desired.

In the accompanying drawings, Figure 1 is Fig. 2 is a front viewthereof. Fig. 3 is a horizontal axial section of Fig. 1, a cartridgebeing shown in dotted outline. Figs. 4, 5, and 6 are views correspondingto Figs. 1, 2, and 3, showing a modified method of applying my inventionto that class of bolts having separate bolt-heads.

In the drawings, the bolt a is shown with recoil projections to a on theopposite sides of its front end. One of these projections is deeplygrooved or slotted for the admission of the ejector for throwing out thecartridgeshells. The other projection is formed with a radial recess'a.The extractor is made in the form of a block f, which plays in thisrecess, and is provided with the usual claw f, designed to engage therim at the base of the cartridge-shell for the purpose of withdrawingthe latter after firing. The blockfis pro vided with lateral guide-ribs,which play in slideways or grooves b 1), formed in the sides of theradial recess a.

Referring to the construction shown in Figs. 1, 2, and 3, on the back ofthe block f, opposite the claw f, is provided a lug f which plays in aradial bore in the projection of. communicating with the radial recess,in which the extractor-body f slides. A screw f the flat head of whichfits into this bore, passes through a hole in the lug f and is screwedinto the material of the bolt a. Between the head of the screw f and thelug f is placed a coiled spring. By this construction the extractor fwill yield outwardly if the claw f, with its oblique face, is pressedagainst the edge of the cartridge-base, as is done in pushing thecartridge home into the barrel by the bolt a, and after having passedthis edge the extractor f will snap back with the said claw f in frontof the rim of the cartridge. The straight guides or slideways b b andthe radial position of the extractor f give to it great stability andstrength. In case the bolt a possesses a separate head coupled with itin any suitable way the extractor just described can be used, or, ifpreferred, it may be slightly altered with reference to the means forimparting elasticity to it. Such a construction is represented in Figs.4, 5, and 6. The bolthead a has wings corresponding to therecoilprojections a of the bolt a. The body f of the extractor is placedin a recess formed in that wing which is not slotted for the shell-ejector. It is guided in the radial grooves or slideways b b in therecessby ribs exactly as hereinbefore described; but instead of being actuatedby a coiled spring the lug f? on the back of the body f is made a flatspring, being elongated toa long tail f which is placed in alongitudinal groove formed in the neck of the head, which neck fitssnugly into the bolt a, and by which the head a is coupled with thebolt. The back portion of the tail f fills up the groove in the neck,but the fore part is made thinner and elastic. The effect is the same asthat of the extractor shown in Figs. 1 to 3 and described abox'e.

I claim as my invention the. following-defined novel features andcombinations, substantially as hereinbefore specified, namely:

to gage said slideways, and provided with a claw at its front and'aspring for pressing it inwardly.

3. The combination, with the bolt having a radial recess in its frontend or head, of a shell-extractor consisting of a block mounted in saidrecess and movable radially therein, provided with a claw on its frontside and formed with a lug on its rear side, a coiled spring in saidrecess behind the block, pressing inwardly against said lug, and a screwpassing through the spring, screwed into the bolt, with its headarranged to close the recess and receiving the reaction of the spring.

This specification signed by me this 2d day of September, 1889.
